Mars

A few months after detecting an "unusually high" level of methane on Mars, researchers have yet to figure out what's causing the spike. They have, however, ruled out one possibility and appear to be getting closer to answering whether life exists on other planets.

Jim Bridenstine weighs in on the latest discoveries from the Mars Curiosity rover.

NASA's eventual goal is to put astronauts on Mars, but the space agency's Curiosity rover is keeping it busy in the meantime. In a new blog post, NASA said that Curiosity is still exploring the Gale Crater and uncovering the mysteries of the "clay-bearing unit," where it's using its tools to drill into the Martian soil.

Three and a half billion years ago, a blood-red wall of water as tall as a skyscraper may have hurtled across the surface of Mars, inundating an area of land larger than the United States.

NASA may have ambitions of returning to the Moon on its own, but it's asking for help from Jeff Bezos and Elon Musk to make breakthroughs for future space missions, including going to Mars.

Talk about robot power. A time-lapse video shows NASA’s 2020 Mars Rover performing a very impressive ‘bicep curl.’

A dramatic video shows the moment when SpaceX aborted its attempt to “hop” its’ Starhopper rocket prototype 65 feet into the air.

While astronauts floating around in the International Space Station (ISS) would have access to exercise machines to counteract these effects, they would have no such equipment on Mars. The gains they'd have from pumping iron at the Gold’s Gym ISS would be gone fast. However, researchers might have found a dietary supplement that can counteract this problem: resveratrol, an antioxidant found in grape skin, blueberries and perhaps most famously, red wine.

Jim Bridenstine says you have to go to the moon to get to Mars.

Tom Jones reflects on where he watched the Apollo 11 moon landing and what impact it had on the country.
